I believe Pangolin and somewhere on PL there is a diagram showing how to connect two +24V power supplies together to get a +24v/-24V differential. I don't have a link handy for you though. There should be several historic discussions of it if you do a bit of searching through PL.
Alternatively, there are suppliers that make a +24V / -24V power supply. For example Digikey sells five including this one: http://www.digikey.com/product-detai...319-ND/1634157 I have also found some on AliExpress after looking for a long while.
Sorry, but I don't have any knowledge of continental European suppliers though.

All I find are sources of 24v. But none with the possibility of + -24V using common as "neutral".
I tried searching even with the reference power supply manufacturer, but can not find any replacement.
Do you know where I could find a (reasonably priced) or could solve the problem with a similar source?
Best Regards.
